Document Type and Number:
WIPO Patent Application WO/2015/030381
Kind Code:
A1
Abstract:
Disclosed is a partition-type floatation apparatus including a reaction chamber (110) and a bubble generating unit (120). The reaction chamber (110) is connected to a sewage inflow pipe (111) and has a treated water discharge hole 112. Within the reaction chamber (110), lower partition walls (113) extending upward from the bottom and upper partition walls (114) extending from the top are alternately installed to form a plurality of bubble reaction zones (115) therebetween in each of which suspended solids are floated and removed. The bubble generating unit (120) generates fine bubbles (B) having a micrometer or nanometer size and injects the generated fine bubbles (B) into the sewage (10) supplied to the inside of the reaction chamber (110) using the sewage supply pipe (111) and a bubble supply pipe (121) or using a bubble sprayer module (165) installed within at least one of the reaction zones (115).
